Climate Hope

October 18, 2019

Mario and the Hole in the Sky is based on the true story of Mario Molina. He was a Mexican scientist who helped solve a big problem. Molina was worried about a hole in the ozone layer over our planet. The ozone layer provides protection from the sun’s rays. Molina found that certain chemicals were causing the hole to form. He worked with governments to ban them.

Now the hole in the ozone layer is shrinking. For their work, Molina and his colleagues were awarded a Nobel Prize.

Elizabeth Rusch wrote the book. She told TIME for Kids that Molina’s story mirrors the challenges we now face in fighting global warming. “It can feel really overwhelming, but international cooperation helped fix that problem,” she says. “And it can help with climate change, too.”
